According to the Environmental Protection Agency (EPA) there are up to 7500 contaminants found in tap water. Out of these 7500, the EPA has identified 600 that they believe may represent a public health concern. Despite this, the EPA currently regulates less than 100 contaminants and has not updated the water safety rules for over thirty years. There are three types of contaminants in water: organic and inorganic chemicals and biological contaminants. AquaTru is designed to remove all three types of water contaminants.
